Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue arises when a lower file's size is changed underneath overlayfs, causing an assertion in the copy up data loop. This type of use case is documented to cause undefined behavior. Returning an EIO error for the copy up makes sense, but it should not be causing a WARN ON assertion.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
